BOX-COVERING MACHINE.

SY'ECIFICATION forming part of Letters Patent No. 585,820, dated July 6,1897. Application filed December 11, 1896. Serial No. 615,257. (Nomodel.)

To ntZZ whom it mayco'ncern;

Be it known that I, HORACE INMAN, a citizen of the United States, and aresident of Amsterdam, in the county of Montgomery and State of NewYork, have invented certain new and useful Improvementsin Box- CoveringMachines, of which the following is a specification.

My invention relates to improvements in box-covering machines. Thegeneral construction and operation of such apparatus and the workperformed by them in the manufacture of paper boxes are now so wellunderstood that the following description may be limited to anexposition of the specific construction embodied in my invention, itbeing understood, however, that it is applicable to machines forapplying a single strip of covering-paper to boxes, or more than onestrip, as may be desired.

Figure 1 illustrates an elevation of the ma chine. Fig. 2 illustrates aplan thereof. Fig. 3 illustrates a detail of certain of the paperguidingdevices. Fig. 4 illustrates a detail of the stop-motion devices asapplied to the driving-Wheel. dinal View, mostly in section, of theparts shown in Fig. 4, with the addition of the stoppin mechanismactuatedby foot-treadle. It is taken on the line 6 6 of Fig. 6. Fig. 6illus trates an elevation of the parts shown in Fig. 5, taken on theline 5 5 in that figure. Fig. 7 illustrates a plan view, partly insection, of the preferred construction of the box=formrotating andpaper-cutting devices. Fig. 8 illustrates an end view inelevation of theFig. 9 illustrates a detail in elevation of certain parts of theboxform-rotating devices. Fig. 10 illustrates an elevation of certainother parts of the boxform-rotating devices.

A is the base of the machine. B is the standard thereof. 0 is the platenor table. All these parts are preferably made of castiron. Above theplaten extends a tubular post D, which is bored horizontally near itsupper end to receive a rod or bar E. This rod is grooved longitudinallyon one side, as at F, (see Fig. 1,) and a spline or feather in the upperpart of the post engages with this groove, so that rotation of the rod Eis pre- Fig. 5 illustrates a longitu vented, and yet it may have,longitudinal movement through the post. A set-screw is preferablyemployed to fasten the rod at any desired position.

G is a glue-tank, preferably double-bottomed, so that steam may beintroduced at H for warming the adhesive material.

I is the glue-roller, which is journaled upon a shaft J and so locatedas to revolve in the adhesive material within the tank. It is or may beprovided with a ratchet K and pawl L to prevent backward movement.

M is a scraper which may be adjustable and of any desired construction,preferably, however, the kind in which two parallel bars separated by ashort space are adapted to rotation in their bearingsas, for instance,by the hand-wheel Nso that the paper which passes between them may becaused to rub with greater or less force against one or the other,dependent upon their relative position. This form of scraperis now wellknown and does not require further description.

0 is an arm pivoted to a stud P on the side of the glue-tank, and theposition of this stud may be changed by loosening the nut Q on theinside of the glue-tank to give the arm 0 a horizontal or vertical or anintermediate position, so that the location of the reels of pa per whichare supported upon a shaft R, which is fastened in the end of the arm 0,may be changed relative to the roller I.

S S are two flanges,which may be solid or made in the form of bars, asseen clearly in Fig. 1, and which confine the paper laterally. They areadjustable on the rod R by means of the set-nuts T T.

U is a cross-rod or stiff wire the ends of which are bent downwardly andpass through studs V and Von the sides of the glue-tank. The rod isfastened at any desired height by means of set-screws W W, so that anydesired adjustment and tension of the paper may be acquired, for it willbe understood a is a cross-rod upon which are located guiding-fingers b,which project downwardly (see Fig. 1) and act as guides for the paper byimpinging upon the edges thereof. These lingers are movable upon the bara and may be clamped in any desired position by small set-nuts c. Thebar is supported at one end only upon a stud d ,which rests upon a lug6, cast or otherwise formed upon the glue-tank, so that the paper can beswung under it quickly in preparing the machine for work.

f is a small plate or table adapted to support a pan f or otherreceptacle to catch any adhesive material that may be squeezed out frombetween the papers. This plate has a hub g upon its under side, which isbored so that it may slide upon the rod E. 1 This part of the apparatusis best seen in Fig. 3. At each side of the plate fare two ears or lugsh h, upon which are supported two uprights 2' 1', upon which in turn aresupport-ed a crossrod j, having on opposite sides links lo respectively,and Z is a cross-bar which connects the upper ends of the uprights i 2",and upon this cross-bar are a series of guidingfingers m m m m They areall supported upon small hubs, as shown, in which are threadedset-screws 'n at a 72 These devices are used when two or more strips ofpaper are employed to cover the boxes, the guiding-fingers beingproperly located and manipulated to impinge upon the edges of theseveral strips of paper and to guide them all, as set forth in thereissued United States Letters Patent granted to Horace Inm an the 13thday of February, 1883, No. 10,286, to which I refer for a detaileddescription. It is not essential, however, that the paper-guidingmechanism should be of this particular character, nor is it essentialwhen a single strip of paper only is used that guiding devices of anykind should be employed. The form illustrated, however, has been foundeffective and valuable and is therefore illustrated in connection withthis machine.

0 is a tubular sleeve grooved on one side, as shown at 19. It passesthrough a rounded knob or upper end of the post D, above thelongitudinal rod or shaft E, and has within ita shaft q, upon one end ofwhich is loosely mounted a belt-wheel 7' and on the otherend a beveledgear 5, which meshes into another beveled gear '6, which is mounted upona longitudinal shaft a. This shaft is grooved, as at c, and a feather onthe inside of the hub of the beveled gear 6 engages with this groove, soas to have a spline elfect to compel the rod u to turn with the pinionand yet allow the former to be moved longitudinally through the pinion.The parts are contained within a yoke w on the end of the sleeve 0 andare retained in position by it partly.

a (see Fig. 2) is an arm having a hub at both ends, as shown. One ofthem embraces the longitudinal rod E and the other embraces the hollowrod 1), and set-nuts c and d cl, respectively, clamp these parts intheir desired position and yet permit longitudinal movement oradjustmentof them, as the necessities of the work require. Thus themachine as a whole, and also the relation of its several parts to eachother, can be adjusted, as desired, to accomplish the best results inconsideration of the character of the paper or adhesive material beingused and the kind of work produced. Upon the hollow rod Z) are mountedthe cutters e, paper-guiding fingers f-, and box-form support g, whichis actuated by suitable mechanism contained within the terminal portionh of the rod 1). These cutting-off devices may be of any desiredconstruction. I therefore, excepting as specifically claimed, do notlimit myself in regard to them. I shall, however, hereinafter describe aspecial construction of cut-off mechanism which I prefer to use inconnection with this machine and claim the same as part of theimprovements protected by this patent.

Referring to Fig. 2, f are paper-guiding fingers set upon elasticsprii'lg-supports or brackets it, which are suitably fastened to a sortof hub 0 and the paper on its way to the cutters passes between and issupported by them, so that when it is cut off by the action of theshears the remaining end is supported by the lower finger, and if thesevered end should stick to the swinging blade of the shears, by reasonof its becoming more or less smeared with adhesive material and becarried upwardly by the blade when it rises, the paper will thenimmediately strike against the upper bar and be stripped off or pulledaway from the swinging blade, and yet,owing to the elasticity of thesesupporting devices, they will readily yield somewhat to the pull of thepaper, thus avoiding tearing of it should the strain be considerable.

p is a cross-rod supported upon an upright g, which is fastened in thearm a at any desired height, and upon it are paper-guiding fingers r 0",which may be the same as the fingers I), already described.

Referring to the parts shown more particularly in Figs. 4, 5, and 6,they illustrate devices whereby to a certain extent the opertor is notin control of the machine-that is to say, after he starts the machine bypressure upon the pedal it continues to run irrespective of anything hemay do until the box upon the box-form has made one complete revolutionand should be completely covered with the covering or covering andtrimming papers, with the result that not only are the operatorscompelled to be active in their work of rubbing down and edging over thecovering-papers, but also there is no possibility of there being slackin the coveringpapers, which is likely to occur to the detriment of thework where the machine can be stopped and started at any moment by theoperator. The parts that effect this purpose are as follows: Thedriving-wheel 7" has arccess A in its hub, the peripheral surface ofwhich is provided witha series of ratchet-like teeth B, in the recessesbetween which works a pawl O, which is pivoted, as at D, to an annularblock E, which is keyed, as at F, to the shaft q. The pawl 0 works in arecess G made in the block E, and a spring H normally throws the pawloutwardly into engagement with the teeth B. I is apin which projectsbeyond the surface of the block E. J is a block or forging fastened by asetscrew K upon the exterior of the sleeve 0, and it supports a pin L,which is normally thrust to the right by a spring M, but which can beforced rearwardlyby a bell-crank N, which connects at O with thetreadle. The bell-crank is pivoted at P to a lug projecting downwardlyfrom the block J. Q, is a swinging latch actuated by a spring R, whichwhen the pin L is retracted swings across its retracted end, as seen inFig. 6, in which figure it is shown as in the act of passing across oronto the end of the pin L, and becomes locked against outward movementby entering a groove cut in the side of a projecting pin S. Theoperation of this part of the apparatus will be now recited, since itwill be more easily comprehended if given in immediate connection withthe description of the parts. It is as follows:

The belt or driving wheel r, as stated, is loose upon the shaft q, andwhen the pin L is in its inward position it engages with the pawl O andlifts the same out of the recess between the teeth B in the hub of thedriving-wheel, so that its movement is not conveyed to the shaft q. Nowtherefore to start the machine the operator presses upon the pedal,which, through the instrumentality of the bell-crank N, retracts the pinL. The spring H then immediately projects the pawl (1, which instantlyengages with one or the other of the recesses between the teeth B, andthereupon the rotary movement of the beltwheel 4" is conveyed to theshaft q and the apparatus starts. Simultaneously with the withdrawal ofthe pin L of the pedal the latch Q, actuated by its spring R, passesacross the retracted end of the pin L, so that it cannot again returninto the path of the pawl 0. Consequently whatever the operator may dowill have no effect upon the movement of the machine. The shaft Q willcontinue to revolve whether or not the pedal be pressed upon. During therevolution of the parts, however, the pin 1, which is fastened to butprojects beyond the face of the block E, is

brought around until it engages with a pro jecting thumb T, which formspart of the latch Q. As soon as this takes place that latch is forcedoutwardly against the action of its spring R, and thereupon the pin L isreleased and itimmediately springs forwardly .into the path of the pawlO, which, however,

at this stage of the movements has passed beyond that pin, so that itcompletes its revolution before it comes in contact with the pin L,whereupon the impact of that pin against and box form rotating instrumentalitiesthey may be made, as before stated, in any preferred form.One desirable construction is shown in Figs. 1 and 2. My preferredconstruction, however, is shown in Figs. 7 to 10. The advantages whichthis form has over all others is that it is simple, short in space, andits construction allows the cutter-blade to act nearer the box-form, sothat when desired the covering-paper can be cut practically at the verycorner of even a small box; also, the two parts of the box-form head orrotating mechanism are actuated under this construction by a spiralspring, which is better than a platespring. I also apply a roller to theknifeactuating arm or lever, which reduces friction, and under thisconstruction the boxform is clamped between two nuts on a spindle,thereby permitting a slight lateral adj ustment of the box-form, whichis sometimes very convenient and also makes the change of box-formssimple and easy.

The reasons for the above-stated advantages in the construction shown inFigs. '7 and 10, as compared to those in Figs. 1 and 2, are that thecutter-actuating and box-formrevolving mechanism in Figs. 1 and 2 issupported upon two brackets attached to the sleeve 1), whereas in theform shown in Figs. 7 to 10 these parts are all supported upon an arm 3,which is supported directly from the main bar E of the machine. Thus theout ters may be moved close up to the box-forms, since there is nosupporting-arm in the way, and likewise the number of parts is greatlyreduced, so that the assembling of the machine and the adjustment of itsparts are materially aided.

Referring to the stated drawings, Figs. 7, 8, 9, and 10, I will give theparts numerals as the means of reference instead of letters, so as toavoid confusion of the other figures.

1 is the sleeve of the driving-shaft, which corresponds to the letter I)in the other drawings. 2 illustrates the driving-shaft, whichcorresponds to the letter a. 3 is an arm fastened by set-screw 4 to themain supporting shaft or bar E of the machine. All of the operativeparts in this construction are supported upon the arm E. 5 is a globularbrass casing which incloses the driving mechanism for the box-form,which comprises a mitergear 6, which meshes into another miter-gear 7,which is fast upon the cross-shaft 8. This cross-shaft is journaled intwo bearings 9 9 in each side of the globular extremity 5, and the lowerarc of the miter-gears run in oil which is placed within the globularcasing, so that it is not only a protection against accident arisingfrom these miter-gears, but also serves as an oil-cup for the mechanismcontained within it. Upon the shaft 8 are arranged the two parts of thebox-form clutch mechanism, so called by me. One part 10 is fast to theshaft and the other part 11 has a central extension which enters acentral cavity in the part 10, as shown. (For the purpose of making thispart of the drawings more clear, since they are necessarily somewhatcomplicated, I cross-hatch the part 10 with light section-lines and thepart 11 with heavy section-lines.) The part 11 is held to the part 10 byscrews 12 12, (see Fig. 9,) which pass through the walls of the part 10and enter an annular groove 13 in the part 11. (See Fig. 7.) The part 10is provided with a pin 14, which is fastened to a spring 15 and whichextends through the part 10 from side to side, projecting beyond it, asshown in Fig. 8, and enters a hole 16, which is made at one endof a slot17 in the part 11, so that when the parts are in their normal positionthe spring 15 holds the pin 14 in the hole 16 in the part 11.Consequently the two halves of the clutch are locked together. When,however, the spring is retracted, carrying the pin 14: backwardly withit, then its end again passes through the slot 17, thus giving slightmovement to the two parts of the clutch relative to one an other, andfor the purpose of securing the proper movement of one portion of theclutch relative to the other the part 11 has a pin 18 rigidly attachedto it, which passes through a slot 19, made entirely through the part10. (See Fig. 7.) The end of the pin 18 (see Fig. 8) projects laterallybeyond the side of the part 10, so that in the revolution of these parts(which is indicated by the arrows upon Fig. 8) it comes in contact witha vertically-sliding stop 20, made in the form of a staple and withwhich engages a cam 21, fast on the shaft 8. 22 is an inclined surfacemade upon a suitable part of the machine, with which the extremity 23 ofthe spring 15 engages at the proper time.

The operation is as follows: When the pin 18 comes against the staple20, the revolution of the piece 11 is arrested, and during the time itis at rest the pin 14 (which has just previously been withdrawn by theengagement of the extended end of the spring 15 against the inclinedsurface 22) is traveling through the slot 17 in the part 11. The resultofthe above action is that for a brief period the box-form which isattached to the part 11 does not revolve, nor does the paper travelthrough the machine, and the adj 11stment and timing of the parts issuch that during this brief period of rest the cutters are operated bythe mechanism already described and the coveringpapers cut offsquarethat is, at right angles. Meanwhile, however, the cam 21, which isfast upon the shaft 8 and of course under continuous revo- I lution,engages with the upper or other suit- T able part of the sliding stop 20and depresses it until it attains a plane so low as not to furtherengage with the pin 18, whereupon the spring 24, which is housed in aninterior recess between the two parts 10 and 11, as shown in Fig. 10,and which abuts at its two ends against stops 27 26 upon the said parts,respectively, immediately acts upon the movable part 11, returning itagain to its normal position, and the pin 14 likewise immediatelyreturns to its normal position, since the terminal 23 of the spring15,which carries it, has by this time passed beyond thedeflectingsurface 22. Thus all of the parts referred to again assumetheir initial position ready for a repetition of the operation, which iscontinued in a manner now well understood, the

covered box being removed from the boxform and an uncovered box-blankapplied thereto. By these instrumentalities I secure a peculiarlyvaluable result which has never been attained before, so far as I amawarethat is to say, the parts all operating automatically and withexact positiveness I am enabled by proper adjustment of the parts tocause the severed end of the covering paper or papers to come at acorner of the box, which is a desirable feature, because when the paperterminates at a corner the seam or joint is hardly discernible, evenwith careful scrutiny. In all other machines known to me the lost motionis such as to vary the place of severing the paper, so that itterminates approximately only at the corners of the box, and if removedtherefrom by any considerable space the joint is practically asnoticeable and objectionable as though it occurred in the middle of aside.

I will here state the operation of the devices just above described forthe sake of convenience: The shaft 8 being positively driven by thegearing shown, the part 10 makes continuous revolution with it, and byreason of the engagement of the pin 14 with the hole 16 the two partsnecessarily travel together. When, however,the extremity 23 of thespring 15 comes in contact with the deflecting-surface 22 on the frameof the machine, the spring 15 is withdrawn, carrying the pin 14 with it,

.and immediately thereafter the laterally-projecting end of the pin 18strikes the stop 20, so that the end of the pin 14, which has beensufficiently withdrawn, traverses the slot 17 in the part 11, asindicated by dotted lines in Fig. 9. During the same time the pin 18traverses the slot 19 in the part 10, and it is at this time that thecutting-blades operate and sever the covering-papers, as will beexplained, and in order to bring the parts back again to their normalposition a spring 24 is located in anannular recess 25 in the part 11,which abuts at one end against a stud or pin 26 in the part 11 andagainst another pin 27 in the part 10.

The instrumentalities which actuate the cutters are as follows: 27'is athumb or studlike projection extending radially from the periphery ofthe part 10, which in its revolution comes in contact with a roller 28,which is set on the end of an arm 29, which is keyed to a shaft 30,which carries by a suitable arm 31 a connecting-rod 32, which engages bya thumb-nut or other suitable device 33 with the movable blade 34 of theshears, which is pivoted at a center 35. The fixed blade of the shears36 is set low down, so as to be as close to the box as possible. Thebox-form is fastened by means of a set-nut 37 and milled thumb-nut 38upon a threaded spindle 39, which is attached to the part 11. A spring40, one end of which is made fast to a suitable support such as an arm41, which may be attached to the bracket 3, and the other end fastenedto a lever-arm 42, which is fast by means of a hub 43 uponthe shaft 30of the knives. 4A is a slideway upon which a slide 45, which carries thecutters, is adjusted in any desired position by means of a setscrew 46.The cutting-blades are adapted to any desired elevation by beingprovided with a hub 47 and spider-spring 4:8 for friction, which is setup or loosened by set-nuts 49. A set-screw 50, passing through the hub,engages with a vertically-arranged rod 51, upon which the cuttingdevices slide. 52 is another vertical rod for supporting thepaperguiding devices already described.

It will be seen that the construction of the parts above described andas shown in Figs. 7,8, 9, and 10 is much more compact and simple thanthat shown in the other figures and also that by reason of supportingall of the parts from the single arm 3 there is nothing at the outer endwhich interferes with the cut ters being brought up quite close to theboxform. Consequently I can so adjust my machine as to sever the paperpractically at the corner of a box not larger than one and one halfinches at its largest dimension. This is a great desideratum. And inaddition to this feature the other advantages before referred to obtain.

The operation of the apparatus will be readily understood from theforegoing description, since such machinery in its, general features isnow well understood-that is to say, the reel or reels of paper areplaced upon the shaft R at the left hand of the machine, the flange Sbeing removed for the purpose, and it will be especially observed that,owing to the shaft R being supported at one end only-- 't'. e., by thearm Othe application ofthe coils of paper can be easily and speedilymade to the machine, because all that is necessary is to remove theflange S. If two or more strips of paper are to be applied, I prefer toemploy a dividing disk or flange between the several coils or reels ofthe paper. This is not essential, however. The paper passes from thereel or reels under the bar U, which is adjusted vertically as thenecessities of the work require; thence over the glue-roll I, whichapplies the paste to one side only of the paper, the glue-roll beingcaused to revolve by the pull of the paper over and upon it; thence barpfuponwhich the several papers are united, becoming one by reason oftheadhesive material upon their under sides; thence between the flexiblesupporting and guiding fingers f f thence through the shears or cut ter,and so on to the revoluble or rotary boxform, and the stringing of thepaper through the machine is facilitated, becausein every case where itengages with guide-rods or the like they are supported at one end only,leavin g the other end open, so to speak, so that the paper,or papers,is simply passed around such unsupported end, thus greatlyfacilitatingthe operation of putting the papers on the ma chine.

The apparatus, if driven by steam, is belted in any suitable manner, byreason of the beltwheel T, which actuatesthe parts in a manner wellknown. If power be not employed, the machine, with propermodifications,may be operated by hand by manually turning thebox upon its rotatingform, in a manner well understood. I call particular attention re thefact that this machine is peculiarly simple and durable in construction,that all its parts are adj ustable relative to one tI10l-l1(31,&ll(l areall mounted upon the longitudinal rod E, so that whatever the extensionor retraction of the machine may bein other words, Whether extended toitsutmost length or shortened up to its shortest dimension all of theparts maintain their proper longitudinal alinement, which isa matter ofgreat consequence in apparatus of this character, and that the machinemay be extended or closed up either as a whole or at one end or theother, as required, by simply loosening the set-screws and pulling orshifting the parts along upon the central rod E and rod to to thedesired position, and that the other advantages already referred to arelikewise realized.

I furthermore especially refer to an ad vantageous feature in thismachine which has never, so far as I understand, been heretoforeembodied-that is to say, after the machine has once been started it willinvariably complete a revolution of the box-form, irrethe constructionand timing of the parts is such that as the revolution of the boxapproaches its termination the momentary delay above referred to inconnection with the box-form clutch takes place, during which the paperis severed, and thereafter the machine still further operates for abrief period, revolving the box-form somewhat further, so that the lapend of the severed paper can be rubbed down properly before thedrivingclutch operates to definitely stop the mechanism.

I do not limit myself to the details of con struction described andshown, because it will be evident to those who are familiar with thisart that alterations may be made therein without departing from theessence of the invention.

I do not herein claim, broadly, the combination, in a box-coveringmachine, of an intermittently-rotating box-form, mounted on acontinuously-rotating shaft,with a device on the shaft for actuating acut-off, and means 1 actuated by the rotation of the shaft for unlockingand locking the box-form to it.
